In the velocity selector the electric field is 90,000V/m down and the magnetic field is 0.0053T into the page. An electron is shot through the velocity selector and then enters a region of a magnetic field that has a strength of 0.00242T into the page. If the radius of curvature of the electron is 4 cm . Calculate the mass of the electron.

Aspecial electronic sensor is embedded in the seat of a car that takes riders around a circular loop-the-loop ride at an amusement park. the sensor measures the magnitude of the normal force that the seat exerts on a rider. the loop-the-loop ride is in the vertical plane and its radius is 23 m. sitting on the seat before the ride starts, a rider is level and stationary, and the electronic sensor reads 740 n. at the top of the loop, the rider is upside down and moving, and the sensor reads 370 n. what is the speed of the rider at the top of the loop?

Atelevision set that has been running for a while heats up even the air around it. which two laws of thermodynamics could be used to analyze this scenario

What organization and environment is described above?
